Just picked up one of these on our favourite auction site for £40 to test 8)

I have the TP Link Archer C9 at the moment, but the firmware is really buggy, and the Super Router isn't an option as thats even worse!

I see Kitz has a thread with all the firmwares there, but lots of the links are broken? Especially the links to the "Stable" firmwares? The ZyXEL Ftp site seems to not be working either.

 I'll probably try this out in Bridged mode too, and thanks to Kitz for her helpful guide on the main site

Thanks very much Chrysalis!

Hopefully will be arriving tomorrow, seems there's a newer modem driver than my Super Router - so maybe we will see how it goes.

Obviously the Super Router caused some issues with the line, so I want to see if this router does any better, I'll keep all informed.

[les-70]

 I will be interested in what you find.  For me the Zyxel was a bit worse than the super router when it came to errors.  As I have noted before I think that although the 63168 chipset modems are reported to be great on quiet lines they are potentially bad on noisy lines, and especially so if there are odd noise spikes.

As I have noted before I think that although the 63168 chipset modems are reported to be great on quiet lines they are potentially bad on noisy lines, and especially so if there are odd noise spikes.

This is basically my line, so I think the cause of me going back on a banded profile was when I reconnected the Super Router, this let to the banding being re-applied the following morning.

What router are you currently using on your line?

[kitz]

Ronski's line can be quite noisy at times.  He's been averaging about 1400 E/S per day on the Zyxel and I notice last week hit >1700 but the DLM left him alone and he's still not interleaved.   He previously used a HG612, whereby he was interleaved.  Since using the Zyxel he immediately sync'd at a higher rate and has fared better with DLM.  -  DLM has also not only reduced interleaving but removed it completely.  Ronski's line certainly seems to perform much better with the Zyxel. 

Its going to have to be a case of suck it and see, but in all honesty most lines do seem to see an improvement.  I think there's only les thats seen worse and chrys who saw more E/s.  Les seems to think it could be the chipset and he may be right in that it expects the line to be using g.inp.  The only other thing that I could possibly think is that perhaps it doesnt like being capped and somehow doesnt take into account the 'surplus' SNRm   I dunno how that would work though, plus its just dawned on me that it didnt seem to bother with ronski & g.inp.   Its most likely to be something to do with one of the noise protection algorithms, of which several will be in use (TCM, RS, INP/G.INP) and the type of noise experienced.

Interesting, the Super Router uses the same chipset (but an older driver), so I'm hoping the Zyxel will be better - plus I can get line stats from it - I don't know why or for what reason the Super Router caused DLM to revert (likely ES count was too high).

I'm still also trying to work out what Speed profile TalkTalk use for DLM, I've always assumed Stable because of the IPTV, but I'm not sure as many posts on the TalkTalk forums say Standard.

If it is stable then I'm very wary that 72+ es per day will cause the line to go amber, and that's not something I want at the moment as I'm nearing the end of my caution count atm. EDIT: 12:10 had my banding moved up 10mbps

It's arrived, turns out it came from KCOM

My line always seems to lose interleaving through the winter months IIRC, but it performing much better than it has ever done for any length of time.

I've attached a couple of graphs I done some time ago which runs from 20 Aug 2012 to April 2014, sometime I'll attempt a graph of the entire period.

Edit: I'm averaging 1410 ES a day at the moment

Hooked it up earlier, however tried and failed to get bridge mode working

Anyone on TalkTalk using this router know the settings? As they don't PPoE for authentication just normal Dynamic IP?

Attainable went up from 84,000 to 90,000kbps though, similar to the Super Router. Didn't keep it connected though as needed to put the HG612 back to do some more Googling!

[Chrysalis]

check my posts in a zyxel bridging thread and also kitz based on those posts added a zyxel bridging guide to her site.

Seems I worked out what I did wrong, I'll have another go at setting it up tomorrow at some point. 6b1 is the firmware I'm going to use to start I think, newer version of the adsl_phyl than the Super Router.

Seems my attainable has gone up, but the SNR Margin is up by about 0.3dB, shall see if it stays stable like before.

Going to now monitor the ES count, as I think with the Super Router - which has the same Broadcom chipset, this is what was causing the issues.

[les-70]

  With your speed banding you might have expected a bigger snrm increase of at least 1.0 db.

 It will be hard to compare with the super router now that you are interleaved.  Your current ES rate in not large and the DLM might in any case back off given time.  The 63168 devices may or may not be better or worse when interleaved, it will be interesting to see.  If do you go back to fast path I would keep a very close eye on the errors and quickly try the HG612 again if the error rate is looking large with the Xyxel.  You only need one bad day to set off the DLM downwards, but many days to get back up.

Good luck, it will be interesting to see your results
